Filed: 1989-04-18
Abstract: PURPOSE:To enhance a withstand-voltage characteristic and a physical stress- resistant property by a method wherein a dielectric film at a fragile part of a capacitor element is made locally thick. CONSTITUTION:A 0.3mm phi anode lead 10 which has been implanted into a sintered substance 12 is constituted of a metal member identical to that of the sintered substance 12. A liquid of two layers formed by filling a hydrophobic solution 14 at a specific gravity of 1.5 or higher into a chemical-formation tank 15 and, in addition, by filling a conductive aqueous solution 13 at a specific gravity of less than 1.5 is used as a chemical-formation liquid; a capacitor element is immersed so as to be stretched over two layers. That is to say, a surface part of the capacitor element is immersed in the conductive aqueous solution 13 and parts other than it are immersed in the hydrophobic solution 14. An anodic oxidation operation is executed at a voltage which is higher than a prescribed rated voltage; a locally thick dielectric film can be formed in a part which has been immersed in the conductive aqueous solution. Thereby, a defect rate of products is reduced as compared with uniformly chemically formed solid electrolytic capacitors; in addition, a withstand voltage characteristic can be enhanced.

IPC: H01H33/66
Filed: 1988-04-22
Abstract: PURPOSE:To improve the interrupting performance by providing a metal spacer, partly coated with an inorganic insulating material, between the main electrode and the coil electrode and eliminating a leakage current flowing through the spacer and generating a sufficient longitudinal magnetic field. CONSTITUTION:A spacer 5 is formed by coating an inorganic insulating material 6 such as ceramics on the surface of a metal cylinder 5a made of stainless steel, etc. There are various coating methods, but the alumina ceramics coating by plasma jet melting method is most suitable from the viewpoint of manufacturing processes. To assemble a vacuum valve, silver soldering at a high ambient temperature of 800-900 deg.C is required, but as a plasma coated film has air holes, even if there is a large difference in thermal expansion coefficient the air holes absorb and relax the stress, so that the peeling of the film will never occur. Owing to the insulating performance of the spacer 5, the total interrupting current flows through the coil electrode 2 and a strong longitudinal magnetic field is applied between the electrodes to improve the interrupting performance and moreover an electrode structure with a high mechanical strength can be obtained.

Title: Embossed sheet
Inventor: TERADA MASATARO
IPC: B32B27/00
Filed: 1990-04-14
Abstract: PURPOSE:To mass-produce embossed sheet at a low cost by a method wherein embossing is developed simultaneously through recessed and projected wrinkles due to the thermal shrinkage of foamed layer at the thermal bonding in a sheet forming process. CONSTITUTION:Surfacing material film is formed by dry-bonding polyester film 1 through gum 2 on the surface side of polyester film 3, on which aluminum 3a is deposited. By welding foamed polyethylene sheet 5 through polyethylene 4 with an extruder onto the rear surface, onto which anchoring material A is applied, of the surfacing material film, sheet equipped with foamed layer on the rear surface side is produced in composite form. Further, on the foamed layer side, onto which anchoring material B is applied, of the sheet, linear loading polyethylene film 7 is welded through polyethylene 6 with the extruder. Since the foamed layer is rapidly shrunk thermally so as to develop recessed and projected wrinkles at this time, the aluminum-deposited film 3 and the polyester film 1 of the surfacing material, to which the foamed layer is bonded, are drawn up by the shrunk foamed layer, resulting in developing emboss due to the recessed and projected wrinkles on the front surface side of the surfacing material. Thus, the simple and rapid mass-production of the subject embossed sheet becomes possible at low cost.
